With the MRT AfterCat H-Pipe for 2012-2013 Boss 302 Mustang, deep, performance sound can be achieved even on a budget. This systems H design maximizes total mid-pipe volume to give that classic, muscle car exhaust note we all know and love. MRT engineers have optimized tube diameter and smoothness of the exhaust path in order to minimize restriction and power losses. The factory mid-pipe is 2.25 inches in diameter at the point of restriction. The AfterCat H-Pipe improves exhaust flow by widening mid-pipe tube diameter to 3 inches. CNC mandrel bending technology ensures a smooth exhaust path and precise fit.

The 2012-2013 Boss 302 AfterCat H-Pipe is manufactured right here at the MRT Headquarters using the highest grade 304 Stainless Steel to provide superior corrosion resistance. We stand behind all MRT exhaust systems with a LIMITED LIFETIME WARRANTY. Because the AfterCat H-Pipe reuses your Mustangs factory catalysts, no tune is required for installation and emissions aren't affected. This system is a direct bolt on replacement, no drilling, cutting or welding required.

Great h pipe August 22, 2016
Reviewed by: Juan from Kyle , TX United States  
I add the stock boss h pipe to my 2014 GT, it was good but I wanted something a bit louder and deeper. So I got this one...

And WOW it's louder and deeper. I have the side pipes wide open. Can be a bit loud at times. Might add the QTP electronic valves or go with a small disc plate.

MRT all the way!!!
